Now that more people have received the BlackMagic Pocket Cinema Camera, there are dozens (if not hundreds) of comments and questions about solutions for poor battery performance.

At the time, I had just a few days to work with the camera and needed to come up with a quick solution, so I ran over to the electronics store and fashioned up a DIY adapter cable to work with my Tekkeon MP3450i batteries (love these things).

I wasn't quite sure how long each battery would last, but during a full day of shooting I only needed one battery (and it wasn't even drained at the end of the day). I'm not saying this is a perfect solution, but it's one that I had to work with and can guarantee it does work quite well while we're still waiting for other affordable solutions from companies.

Here are a few images on how I created a cable with a female connector to one side, and the correct male barrel on the other. This charges the battery inside of the BMPCC as well as powers it. The next time I have a chance, i'll actually do a full test on actual run time.
